Here are eight things Britons are less likely to die of today than only a few decades ago - although in many cases improvements have slowed in recent years, and modern life has brought new problems too.

1. Winter

More people die in winter than in summer because of cold weather and higher rates of infectious illnesses such as flu.

But the difference between the number of people dying in winter compared with summer has fallen since the 1970s, when it averaged more than 40,000 extra deaths.

By 2015-16, there were fewer than 25,000 excess deaths a year in winter compared with in summer.

Much of this is because of general improvements in health, but our homes are also better heated and insulated now.

These days almost all homes have some form of double glazing but in the early 1970s fewer than 8% did, according to The Ministry of Housing, Communities and Local Government.

Despite an overall downward trend in winter deaths, there are significant fluctuations year-on-year. That can be because of a particularly cold winter or bad flu strain.

The highest number of excess winter deaths in recent times was in 1999-2000.

"The main strain of flu that year affected older people more than the young, which likely contributed to the high number of winter deaths," says Dr Annie Campbell, from the Office for National Statistics (ONS).

But if you look at the whole winter period so far, figures from Public Health England suggest that there have been fewer excess deaths among the over-65s than the year before, or in 2014-15 when the strain of flu used in vaccines turned out not to be as good a match as usual to the main strain circulating that winter.

2. The workplace

There has been a big drop in fatal injuries at work since 1981.

Before then, not all industries were required to report workplace injuries, so the data is patchy. But in the industries that did have to report, deaths fell sharply in the 1970s too.

In the year 1986-87 there were 407 fatal accidents in workplaces around Britain. Three decades later the figure had fallen by two-thirds.

The size of the workforce has increased a lot in that time, so if we look at the death rate per 100,000 workers, the improvement is even greater.

This is largely because of Britain's transformation from an industrial economy to a service-based one. Clearly people working in factories and heavy industry are more at risk of fatal accidents than office workers.

But these days the figures may be underreported, says Noel Whiteside, a public policy expert at the University of Warwick.

The number of self-employed people is rising rapidly, making incidents harder to track. If a contractor is killed in a car crash on the way to a job, or has a heart attack while working from home, that would not count as a death in the workplace, she points out.

There are other reasons to temper optimism with caution.

Although workplaces are safer now, people generally work longer hours, and it is hard to measure the effects of health problems brought about by overwork. "I don't think white-collar work was nearly as stressful 40 years ago," Whiteside says.

Improvements in general health levels are one reason for a decline in workplace deaths, but "there are some signs in the last two years that life expectancy has started to fall," says Whiteside.

3. Infancy

The death of a baby is far rarer than it used to be. In 1900, one in every six babies died before their first birthday. In 2015, it was one in 270.

In 1964 the mode age of death was zero, meaning more people died at age zero than at any other age. The most common age at death is now 85 for men and 88 for women.

In more recent decades, infant mortality has continued to fall sharply. The prevalence of stillbirth has also plummeted.

One key reason is that levels of smoking and drinking alcohol during pregnancy and early motherhood - big risk factors - have fallen sharply.

Sudden infant death syndrome, or "cot death", has become much rarer since the 1980s.

This is largely attributed to the Back to Sleep campaign, which launched in 1991 and recommended that parents didn't share a bed with their babies, and put them on their backs.

4. Britain's roads

A third as many people died on Britain's roads in 2016 as did in the early 1980s. We drive more now, so the improvement in road safety is even more dramatic than the graph suggests.

Although all new cars have had to be fitted with seat belts since 1966, wearing them became compulsory in the front seat only in 1983, and in the back in 1991. These legal changes were accompanied by hard-hitting advertising campaigns, which helped change cultural attitudes.

Better safety measures in public swimming pools have also led to a reduction in deaths, from about 50 a year in the late 1970s.

These days incidences of drowning in local swimming pools are vanishingly rare, despite the fact that more people use them.

However, the way data is collected has changed over time, making it difficult to make direct comparisons.

6. Cardiovascular disease

Cardiovascular disease- both heart disease and strokes - is still one of the biggest killers in the UK. But fewer people are dying from it than they were 50 years ago, partly because of better diagnosis and treatment.

The introduction of a technique known as percutaneous coronary intervention to treat heart attacks - by widening the arteries using a small tube called a stent - has also improved survival rates.

The growing use of cholesterol-lowering statins from the mid-1990s onwards led to gradual improvements in mortality.

However, big improvements were seen before many of these medical interventions were introduced, mainly driven by a better understanding of the impact of lifestyle factors such as diet and exercise on our health.

In particular, people began smoking less and eating less saturated fat - though some of these gains have begun to be offset by a rise in obesity.

In 1971, heart disease caused most deaths in the UK, killing about 330,000 people. By 2015, this had fallen to just under 160,000, about a quarter of all deaths.

Despite improvements, heart disease still kills more men and women in England and Wales than any other disease except dementia and - while treatment has improved the chance of survival - more people are now living with heart failure and its effects.

Life expectancy has increased by 13 years since the foundation of the NHS, which is something to celebrate - but an ageing population is bringing new pressures.

7. Smogs

The big killer smogs that plague cities such as Delhi and Beijing are a thing of the past in Britain.

In previous decades, though, it was not uncommon for smogs to kill several hundred people in only a few days.

Households and factories used to burn a lot more coal - and in certain atmospheric conditions, the dirty air would not disperse, says Peter Brimblecombe, whose book The Big Smoke looks at London smogs between the 1870s and 1970s.
